Lester B. Pearson International Airport Terminal Development (GTAA)

Lester B. Pearson International Airport is an international airport serving Toronto, Ontario, and its metropolitan area. The airport is named in honour of Lester B. Pearson, the 14th Prime Minister of Canada, and is the largest and busiest airport in Canada. The development project involved replacing the original Terminal One and a portion of Terminal Two.

Our Role

Walters Inc. provided Design Assist, supply and installation.  The project included a central processor, liner, control tower, Pier E, baggage handling, and falsework.

Overcoming Challenges

Working on an operational airport created several issues with site logistics. Given that air traffic was continuing over the site during construction, we had to work with reduced crane ceiling height restrictions that required creative crane configurations and movement to accommodate. Post award we were also notified of impact reducing our allotted assembly area on site for the large HHF pre-tensioned kingpost trusses.  We developed means and methods to build, pre-tension, and ship these 19 foot wide assemblies from our plant.

There was also difficulty managing the schedule flow with major design changes resulting from changing passenger security separation requirements.
